I don't think that the electric fences that are made for dogs are bad...they don't bother me at all, just a small shock....but the ones for horses I hate!! One time, I put my hand on one, thinking that it was going to be like a dog one, and the shcok was sooo strong it blasted up my arm and I litterally flew backwards! I stood there shaking...It hurt so bad...
Leather had an electric collar so she wouldn't jump the fence when she was in heat, and it worked great it was only a small shock, we know cuz my dad put in on himself he's like that...when leather had to have this oitment put on her leg (it was hurt) and the vet told him it tasted really bad so she wouldnt lick it, he took a huge swab of it and put it in his mouth needless to say, it tasted bad...
